Tell us what’s happening:
In the Exercise Tracker Challenge my code is timing out for the last test. Sometimes my code also timeout for other tests. But I am never able to pass the last test due to timeout. However, my code is working perfectly . I even checked the time its taking to process the queries made by the last test and these timings seems to be normal.
The last test is :
" You can add from , to and limit parameters to a GET /api/users/:_id/logs request to retrieve part of the log of any user. from and to are dates in yyyy-mm-dd format. limit is an integer of how many logs to send back."
